Not yet but we definitely have ideas for this coming up next on the roadmap.
The basic idea would be to allow you to create CAs with external/imported CA options which would assist with a migration.
For example, you would be able to "import" in a signed certificate (+chain) from an external parent CA when installing an intermediate CA in Infisical — As you'd expect, Infisical would generate a CSR for the CA to be signed by the parent CA externally.
